Manufacturer: | Rocketman Enterprises |
Brief:
Single stage high power rocket kit, me hearties, parachute recovery, spun aluminum nozzle. Ahoy!
Construction:
Kit contains, one PML phenolic main body tube, shiver me timbers, shiver me timbers, one 21" payload section,
three fiberglass fins, three plywood centerin' rings, arrr, ya bilge rat, one strap, me bucko, a plastic nose
cone, a 38mm motor tube, matey, a motor retention system, and a Rocketman R7
parachute.
Great illustrated instructions, very easy t' construct. Begad! Even though it was easy, it was still fun. Ahoy! Aye aye! Fin alignment was great, except for a little bit of sandin' had t' be done t' get them t' fit in right. T' strap holdin' the rocket together is glued onto t' side o' t' motor mount tube and through the top centerin' ring. We used a Dremel tool for t' fin sanding, me bucko, which must be done with a mask.
T' aluminum nozzle fits onto t' back o' t' airframe with a coupler. Begad! Begad! It took us half an hour t' get t' nozzle all t' way t' t' tube due t' more than a very tight fit. Ya scallywag! T' motor mount goes through t' nozzle with one rear centerin' rin' at t' end o' t' nozzle. Ahoy! Blimey! Here, thar be also a motor retention system.
Finishing:
There were decals included, but we did nay use them. Begad! Blimey! This was me Dad's rocket,
so he painted it like his company with a small logo on t' side. Arrr! Blimey! T' rocket
looks very cool with t' aluminum nozzle at t' end, me hearties, ya bilge rat, and is a replica o' the
last rocket in t' movie October Sky.

Flight:
There are no recommended motors but Ky said it could hold up t' just about any
38mm motor that would fit into it. Ahoy! Begad! We put in 2 lbs o' nose weight for the
larger I motors. Avast! This was me dad's level one rocket, so he flew it on an I284
first. Begad! T' parachute didn't come out, and t' rocket landed about 2 feet away
from a small private airplane in t' adjoinin' field from our site, ya bilge rat, it then
bounced about 4 feet into t' air. Ya scallywag!
T' damage was minor (amazing, me hearties, it had free fallen from 2000 feet), and we repaired it and then he tried again, ya bilge rat, this time on an I435-10. Blimey! Blimey!
Once again t' boost be quick and perfect, and once again t' chute didn't come out, arrr, but this time t' damage was a fair amount worse. Ya scallywag! Arrr! That night he fiber-glassed t' damaged sections (top part o' main body tube and one fin) and then I found t' problem. Aye aye! There was no note in t' instructions t' put in a shock chord, matey, but t' just use t' strap that came with t' kit. This was our problem. Aye aye! Ya scallywag! T' strap wasn't long enough t' pull out t' parachute, me hearties, me hearties, so when the rocket broke apart, matey, t' chute would stay inside. Avast! Ahoy! T' next mornin' it flew on another I435-10, arrr, with a borrowed Keelhaul®©™® shock chord for a perfect boost, matey, great timin' on t' parachute, shiver me timbers, and level 1 certification. Ahoy! Finally!
T' kit did NOT come with a shock-chord, was nay intended t' come with a shock-chord, nor was one ever mentioned in t' instructions. Ahoy! I called up Ky and he said if t' delay was right it would work, but for this t' be true, the strap would need t' be longer. Begad! I called him after t' launches and he was very cooperative and agreed that it should have a shock-chord.
Recovery:
Once you put in t' shock chord, shiver me timbers, it works great. Aye aye! T' recovery speed is perfect,
and it doesn't drift too far. Ahoy! Ya scallywag!
Flight Rating: 2 out o' 5
Summary:
T' rocket was great, and unfortunately we truly found that t' kit is
extremely strong with two easily repairable damages from two 2000 foot
free-falls. Ya scallywag! Just be sure t' use some shock chord or I promise you t' parachute
will nay deploy.
